Unchecky is a free app designed to secure your system against installing unwanted components hidden in installers of popular software.
When you install apps the last thing that you want is to get in your system unwanted components like toolbars, adware or change of the default search engine and home page in your browser. Unchecky will automatically uncheck all offers available in popular installers, protecting Windows against those threats.
Unchecky can also warn the user about accident clicking in option allowing the installer to run potentially unwanted software. The application works in background and detects popular installers offering commercial components that most users are not interested to have in system. Most of those components are also hard to remove.
